Solidity is the programming language used in Ethereum to develop smart contracts.
What is Solidity?
Solidity is a high-level object-oriented programming language used primarily for the Ethereum blockchain. Solidity is a tool for writing smart contracts, which are self-executing code that allows complex automated functions.
It needs to be compiled into low-level machine instructions called opcodes because they are not compiled directly by EVM. Solidity is easy to jump into and easy to write code in, especially for those who already have programming knowledge. It was originally proposed by Solidity and Polkadot founder Gavin Woods in 2014, but was developed by the Ethereum Foundation and the Solidity project team.
It is a statically typed programming language, which means that it prevents type errors and syntax problems by checking program source code. Solidity also supports inheritance, user-defined complex objects and libraries. This enables developers to create new types of complex and automated financial, gaming, auctioning, management and other applications.
It was developed at a time when the Ethereum network was not yet up and running. Consequently, its design needs to be updated to meet modern requirements.
